Chiral phases of liquid crystals.
Chiral nematic phase[edit]
Also known as the cholesteric phase.
Helical twisting power[edit]
The helical twisting power, , determines the pitch of the chiral nematic phase produced when a nematic liquid crystal is doped with a low concentration of chiral solute molecules. [1] [2] [3] [4] [5]
